The keratin cortex stabilizes cells at high strains

Authors Meyer R, Rölleke U, Schwarz N, Perez-Tirado A, Schepers AV, Janshoff A, Köster S Journal BioRxiv Citation bioRxiv 2025.02.24.639846. Abstract The eukaryotic cytoskeleton consists of three filament types: actin filaments, microtubules and intermediate filaments (IFs). IF proteins are expressed in a cell-type specific manner, and keratins are found in

Cortical population coding critically depends on fine-tuning of cell physiology

Authors Revah O, Wolf F, Gutnick MJ, Neef A Journal Biorxiv Citation bioRxiv 2024.02.15.580451. Abstract Cortical function reflects the activities of populations of neurons. How accurately they can encode information depends on the speed with which each neuron can respond to input, as revealed by dynamic gain analysis. Theory predicts

Structures of the 26S proteasome in complex with the Hsp70 cochaperone Bag1 reveal a novel mechanism of ubiquitin-independent proteasomal degradation

Authors Maestro-Lopez M, Cheng TC, Muntaner J, Menendez M, Alonso M, Schweitzer A, Cuellar J, Valpuesta JM, Sakata E Journal BioRxiv Citation bioRxiv 2025.01.22.633148. Abstract The 26S proteasome primarily degrades proteins marked by polyubiquitin chains. Although ubiquitin-independent pathways for proteasomal degradation exist, the mechanisms involved remain poorly understood. Bag1 links
